It is widely believed that reproductive cycles are very similar between human females. However, there are in fact considerable variations both between individuals and within the reproductive life of any given individual. 'Normal' reproductive cycles cover a wide range of eventualities, and the likelihood of successful monthly egg release and ensuing pregnancy can be modified by a large number of factors. In this book, the variability of human fertility is examined by first looking at the physiological processes regulating reproduction, and the roles of metabolic adaptation and metabolic load. Inter-population variation in normal ovarian function is then discussed, covering the importance of factors such as age, disease and breastfeeding in modifying ovarian function. First published in 1996, this is an important book for all those interested in human fertility.

Despite recent advances in our understanding of the genetic basis of human behavior, little of this work has penetrated into formal demography. Very few demographers worry about how biological processes might affect voluntary behavior choices that have demographic consequences even though behavioral geneticists have documented genetics effects on variables such as parenting and divorce. Offspring: Human Fertility Behavior in Demographic Perspective brings together leading researchers from a wide variety of disciplines to review the state of research in this emerging field and to identify promising research directions for the future.

The book that you hold in your hands is the second in a series. The two titles in the series are the following: Genetic Influences on Human Fertility and Sexuality: Theoretical and Empirical Contributions from the Biological and Behavior Sciences Edited by Joseph Lee Rodgers, David C. Rowe, & Warren B. Miller Published by Kluwer Academic Press, 2000 The Biodemography of Human Reproduction and Fertility Edited by Joseph Lee Rodgers & Hans-Peter Kohler Published by Kluwer Academic Press, 2002 The series has published chapters by researchers who study human fertility, from a particular perspective: Biodemography. We welcome your interest and participation in this developing subfield. Or, perhaps, biodemography may be better referred to as a "superfield. " Because biodemography so naturally crosses interdisciplinary boundaries, and because its application draws together researchers from disparate disciplines, it may well be more appropriate to consider that biodemography subsumes a number of other disciplines, rather than the other way around. In this preface, we will describe our own efforts and those of many others to promote and develop the study of human fertility, using methods, models, and theories from both biological and demographic domains. In December, 1997, 25 participants from three different countries gathered in Tucson, Arizona for a small conference with the title "Genetic Influences on Fertility-Related Processes. " That conference represented a fascinating blending of research from two apparently separate domains.

Awarded the W. W. Howells Award for the Outstanding Book in Biological Anthropology, this volume presents a comprehensive, integrated, and up-to-date overview of the major physiological and behavioral factors affecting human reproduction. In attempting to identify the most important causes of variation in fertility within and among human populations, Wood summarizes data from a wide range of societies. Trained as an anthropologist as well as a demographer, he devotes special attention to so-called ""natural fertility"" populations, in which modern contraceptives and induced abortion are not used to limit reproductive output. Such an emphasis enables him to study the interaction of biology and behavior with particular clarity.The volume weaves together the physiological, demographic, and biometric approaches to human fertility in a way that will encourage future interdisciplinary research. Instead of offering a general overview, the focus is to answer one question: Why does fertility and the number of live births vary from couple to couple within any particular population, and from population to population across the human species as a whole?Topics covered include ovarian function, conception and pregnancy, intrauterine mortality, reproductive maturation and senescence, coital frequency and the waiting time to conception, marriage patterns and the initiation of reproduction, the fertility-reducing effects of breastfeeding, the impact of maternal nutrition on reproduction, and reproductive seasonality. This unique combination of comprehensive subject matter and an integrated analytical approach makes the book ideally suited both as a graduate-level textbook and as a reference work.

Fertility rates vary considerably across and within societies, and over time. Over the last three decades, social demographers have made remarkable progress in documenting these axes of variation, but theoretical models to explain family change and variation have lagged behind. At the same time, our sister disciplines—from cultural anthropology to social psychology to cognitive science and beyond—have made dramatic strides in understanding how social action works, and how bodies, brains, cultural contexts, and structural conditions are coordinated in that process. Understanding Family Change and Variation: Toward a Theory of Conjunctural Action argues that social demography must be reintegrated into the core of theory and research about the processes and mechanisms of social action, and proposes a framework through which that reintegration can occur. This framework posits that material and schematic structures profoundly shape the occurrence, frequency, and context of the vital events that constitute the object of social demography. Fertility and family behaviors are best understood as a function not just of individual traits, but of the structured contexts in which behavior occurs. This approach upends many assumptions in social demography, encouraging demographers to embrace the endogeneity of social life and to move beyond fruitless debates of structure versus culture, of agency versus structure, or of biology versus society.

In this innovative and comprehensive work, expanded by one-third for the English-language edition, Henri Leridon integrates biology and demography to investigate human fertility, both natural and controlled. Traditionally, demographers have been concerned with birthrates in different populations under varying conditions, while biologists have limited themselves to the study of the reproductive process. Leridon has formulated the first coherent overview of the functioning of the human reproductive system in relation to the external conditions that affect fertility. The book begins with a readable, authoritative review of human fertility in its natural state. Leridon summarizes and evaluates current knowledge, drawing together rare statistical data on physiological variables as well as demographic treatments of these data. After discussing the classical framework used by demographers, Leridon undertakes a "microdemographic" analysis in which he focuses on the individual and explicates the biological processes through which social, psychological, and economic factors affect fertility. He isolates its components—fecundability, intrauterine mortality, the physiological nonsusceptible period, and sterility—then reviews the composite effect of variation in any one component. Leridon considers situations of controlled fertility: contraception, abortion, and sterilization. The author also presents valuable new data from his own investigations of varying risks of intrauterine mortality. Finally, he shows how the previous approaches can be complemented by the use of mathematical models.

Recent work in quantitative biology has shown theoretically why Fisher's Fundamental Theorem of Natural Selection does not preclude genetic influences on fertility, sexuality, and related processes. Genetic Influences on Human Fertility and Sexuality takes the next step, and presents a number of successful empirical searches for such genetic influence on a broad range of processes, such as puberty, marriage, sexual behavior, and twinning. Employing a broad range of methodological approaches, including molecular and behavioral genetics, this book weaves a new theoretical framework that shows how genes can help relate fertility planning to fertility outcome, and how puberty, sexuality, marriage, and reproduction can be conceptually linked through the genes that contribute to individual differences in the human process.
